My name is Barrie J. Ritter.
My training is in empirical psychology, with Ph.Ds.
in both Sociology and Anthropology, from United States International University,
San Diego, 1988. Recently, I published 64 articles as the National Crime and Justice Examiner,
for Examiner.com, an online newspaper with a public audience. I began in 1975 to conduct
interdisciplinary research on what is now a criminological topic: serial murder
(though this term did not enter common parlance until around 1984.)

I originally gravitated toward this subject out of an interest in the Holocaust, which captured my attention
while I was getting my MA in Psychology at the New school for Social Research, in New York.
